To all whom it may concern:

Be it known that I, 01.10 B. YAW, citizen of the United States, and resident of Arlington, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvemcntsin TypeVVriting Machines, of which the following is a specification.

My invention relates to typewriting inachines and more particularly to the carriages of such machines.

One object of my invention is to provide simple and efficient means whereby the carriage may be readily detached from the machine when desired and a carriage of one character substituted for one of a different character, or whereby the carriage may be removed to give access to the parts beneath the carriage for the purpose ofrepairing them.

Another object of my invent-ion is to provide simple and eiiicient carriage releasing means.

A still further object of my invention is to provide a simple and eflicient construct-ion in a front-strike machine whereby the platen may be swung back to an inoperative position to give access to the parts on the carriage situated below the platen.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of partsand combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the various views, Figure 1 is an enlarged detail fore and aft'vertical sectionalview showing the upper portion of .a. machine embodying my invention. Fig. 2 is a front'view of the same with parts in section and with the platen shown in its swung-back position. Fig. 3 is a detail end view of the carriage and ,feed pinion, t-he finger wheel of the platen being sectioned away. Fig'. 4 is a detail transverse sectional view showing the locking means at one side of the machine for securing the carriage to the main frame. Fig. 5. is a view correspending to Fig. 4 with some of the parts shown in Fig. 4 omitted.

I have illustrated my invention in the present instance applied to a front-strike typewriting machine but from certain as pects of the invention various features may be embodied in other styles of machines.

The frame of the machine comprises side plates 1 united by a. rear cross plate 2 and connected by other transverse connecting means (not shown). Grooved parallel. car flags-supporting rails 3 receive crossed anti v friction rollers l which likewise cooperate and interlock with oppositely grooved c'a-rriage rails 5 on the carriage truck, thus connecting the carriage supporting rails and truck against detachment one from the other but affording a traveling movement of the truck on the rails. The. grooved rails 3 are co 'inected by cross bars or connecting devices 6 which unite the carriage. supporting rails 3 near the ends thereof. These cross bars 6 are apertured near the front ends thereof to receive screws 7. The rear end portions of the cross bars have slots 8 therein for the reception of beaded screws 9. The screws 9 are received at their threaded ends in tapped openings in the rear carriage rail 1 3, whereas the threaded ends of the screws 5 7 are received intapped openings in the forward carriage supporting rail 3. The construction by which the rear carriage rail is connected to the cross barsG near each end of the carriage supporting rail provides individual means for effecting an adjustment of the rear carriage supporting rail near each end thereof so that the rear carriage rail 3 may be brought into parallelism with the forward carriage supporting rail. Set screws 10 are received in. tapped openings in flanges 11 which extend upwardly from f the connecting bars 6 and hear at, their forl ward ends against the rear side of the rear carriage supporting rail 3. The screws 10 thus atl'ord means for effecting a minute adjustnient of the rear carriage rail at each end thereof to bring the carriage supporting rails into parallelism and at the same time provide means Which offer a resistance to the displacementof the rear carriage railfrom its adjusted position. The headed screws 9 likewise operate to clamp the rail to the cross connections 6 and thus afford a dditi onal security against the displacement of the rear carriage rail from its adjusted position.

Ufpwardly extending lugs 12 are formedon anges 13 which'extend' upwardly from -'-:ind vare seemed to cross-pieces 1-1 which are preferably cast or formed in one Ipiece \rith II-Jfhewcarr-iage rails .5 at the ems there If.

that 'there 18: no un'meetimr hetweclrt m 110 a similar manner for cotiperation with the seating the auxiliary frame, comprising the carriage supporting rails 3 and the cross bars 6 which connect them, with the main frame of the machine. Each side plate of the machine is provided with a positioning pin 54 which extends from opposite sides of the plate as shown in Fig. 4 and has an elongated head 55 at one end where it extends beyond the side plate 1 of the machine. The opposite end portion of each positioning pin is threaded at 56 for cooperation with a thumb nut. 57 provided with-a conical looking portion 58. It will be seen that each positioning pin 54 extends at right angles to the slots 53 and is received in transverse slots 59 formed in each of the cross pieces 6 and that.the slots 59 extend at right angles to the slots 53. Adjacent to the slots 59 is a locking depression 60 formed in each of the cross bars 6. The shape of each locking recess 60 corresponds to the shape of the. locking portion 58 on the associated thumb nut 57.

From the foregoing description itwill be understood that when the auxiliary carriage supporting frame is properly seated on the main frame of the machine said auxiliary frame is pr perly positioned and is held against movement both fore and aft and transversely of the machine, whereas when the thumb nuts are screwed in the locking portions thereof-are received in the locking recesses 00 and prevent a displacement or detachment of the auxiliary frame, and the carriage supported thereby, from the ma chine,

By mounting the platen frame in the manner. described so that the platen and platen frame maybe swung back to the inoperative position shown in dotted lines in "Fig. 1 access may be given to the parts situate-d below the platen for the purpose f adjustment or repair. Moreover, the pie en may by these means be swung back to a position-where they are clear ofthe ribbon mechanism ord'inarily' employed in front-strike machines,

Certain of the features shown herein are shown and in some instances are claimed in connection with other features, in the following applications filed by me, Serial Nos. 510,405; 510,404; and 507,920. The claims herein are directed to features not. claimed in nay-said previously filed applications.

Various changes may be made without departing from the spirit and scope of my invention.
